Update.
1998-03-25 Ulrich Drepper <drepper@cygnus.com> * glibcbug.in: Create files safely when mktemp is not available. * sysdeps/unix/sysv/linux/adjtime.c: Make weak alias appear again. Patch by a sun <asun@saul1.u.washington.edu>. 1998-03-25 Thorsten Kukuk <kukuk@vt.uni-paderborn.de> * libc.map: Rename getname to getnetname. 1998-03-25 13:35 Ulrich Drepper <drepper@cygnus.com> * manual/maint.texi: Use supported platform in examples. * manual/install.texi: Document some installation tips. 1998-03-25 10:56 Ulrich Drepper <drepper@cygnus.com> * posix/wordexp.c: Fix some memory leaks and makes $* more efficient. Fix a bug so that it returns an error if a numeric parameter is unset and WRDE_UNDEF is set. Patch by Andreas Schwab and Tim Waugh. * posix/wordexp-test.c: Add new new test. 1998-03-25 Ulrich Drepper <drepper@cygnus.com> * posix/regex.c (regex_compile): Last patch wasn't entirely correct. Patch by Alain Magloire <alainm@rcsm.ece.mcgill.ca>. 1998-03-24 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * manual/filesys.texi (Scanning Directory Content): Fix typo. 1998-03-25 09:24 Bernd Schmidt <crux@Pool.Informatik.RWTH-Aachen.DE> * sysdeps/i386/bits/string.h: Fix all assembler statements so that clobbered registers don't appear as operands.
